The sashimi and rolls here are phenomenal. The quality of food is fantastic (you won't go back to All-You-Can-Eat Japanese buffets after having good quality sashimi/sushi/maki) and the service is great.
I recommend the Japango roll - it has salmon, scallops, and flying fish roe; it's so delicious that I could have eaten the whole serving myself.
The blue fin tuna belly was pricey ($23) for four pieces, but I'd say try it once if you're looking to splurge. It's buttery and it just melts in your mouth.
Be sure to make reservations as this restaurant is really small. Alternatively if you walk in and it's packed, order take-out.
